Thread: Power Hacksaw run off
09/02/2012 02:30:27
Hi folks
 
I suspect that the saw blade is not aligned properly that causes the run off.
I'm in the process of making a compact power hacksaw with ample info from various designs on the web. The frame itself is a 11" G-clamp, heavy for the weight to saw and it will be driven by duplex pulleys of bicycle chain drive and step pulley.
 
I shall look into the 'Run off' problem soon once I get my main saw frame done.
Making a power hacksaw is challenging than buying one. These days bandsaw blades are expensive for model engineers too.

Thread: Blackgates power hacksaw drawings
25/12/2011 16:32:53
Hi all and Bob
 
Thanks for the tips and I like Ady's quick fix for power hacksaw
After some serious thinking...I have to lay off the idea of the Blackgates power hacksaw castings or Kennedy power hacksaw project...seems many parts are not available in my country and the noise of sawing is obvious.
 
Would carry on the old fashion of sawing which I can control the noise level, middle of the night I use a fretsaw instead...though a longer time is needed but I do get the job done in the end.
 
With the bi-metal saw blades in the market, sawing is less taxing now.

Hi Clive & Mark
 
Thanks for the reply! Anyway to send me the link and pdf drawings? I'm open to any simple compact straight forward power hacksaw design.
 
I have an AC 1/3 Hp motor on the stand by and 2 step pulleys...the rest may need to make or hunt for especially the huge flywheel that crank the saw motion...most parts will be in mild steel plates and aluminium blocks.
 
Hopefully, I can construct a compact power hacksaw and could be taken apart for easy stroring. I have been sawing manually, is about time to move ahead as no more younger

Hi Guys
 
Was wondering anyone out there be so kind to scan the Blackgates Power Hacksaw drawings? Need to look at the pulley & belt design and consider worth ordering from Blackgates or make one as I'm far from the UK.
 
May also check with Hemingway but not sure is the design similar to Blackgates which is compact.
 
I'm keen on a compact power hacksaw using normal blades. My biggest steel rod to cut is around 30mm. Hence I hope to build a very small and yet powerful enough to part off steel bar. Most importantly, minimum overhang to cut down the noise as I stay in a flat.
 
Am very grateful anyone would aid me here

Thread: Ground angle tool checking device
04/11/2011 02:33:56
Hi John
 
Appreciate your clear guidance and do agree that simple basic checking and grinding will do a good job. When I read your text, it reminded me of my days in technical training what my workshop instructor would say
 
Once again thanks! A great joy to be here to recall the good old days.

Thread: Press Drill Quill tube in steel or aluminium?
03/11/2011 06:46:39
Hi Ady and Sid
 
Thanks for the note! I'm pleased that your comment is very positive. Yes! I will put the aluminium quill to use, testing its endurance....my used steel quill is being put aside.
 
If this is successful, will make a few more from aluminium rod, as you mentioned easy to machine especially I'm using micro lathe like Sherline. The good point is that the bore hole will not wear that fast using aluminium quill...instead of steel.
 
Here's the photo:


Welcomes anymore feedback

Hi guys
 
Another story to share here. Last week, I bought another China-made bench press drill for spares. This brand is the same with my 6yrs old press drill. I found it so reliable that I got another. To my surprise, after I had taken the machine apart, the quill tube was made of aluminium instead of steel.
 
I was so dismay in the begining but later consider a blessing as I could easily make another once the quill worn out.
 
Wonder is this a good move.

Thread: Ground angle tool checking device
02/11/2011 10:07:48

Hi Guys and Clive

Read all your comments and learnt many! Guess I need not make matters more complicated but resolve the root of the problem by grinding the lip angles correctly.

Many of you have done the basic task of grinding the thread cutter with angle gauge for years which have proven not necessary to have a shadow box magnifier.

Will redo my project again.
Thanks!

Steve

Hi guys
 
Many thanks for the fruitful info!
Yup! The USB microscope is the best solution but it requires a PC and some setup.
 
I'm thinking a small device, handy to keep and simply plug in and view the tool at some magnification.
 
I googled 'profile projector' that's the commercial device availabe. With this design in mind I think whether I can make a simple version using a graphic enlarger projector which is avaibale in graphic stores. It will work like the over-head projector instead of projecting an image on the screen, it would reflect on a frosted screen. Focusing by moving the lens along a vertical axis.
 
Will do more research here

Hi folks

Just the other day, I spoilt my 2 day turning job at the last stage of thread
cutting. The thread turned out too sharp and thin walls.

My threading tool was not correctly ground. What's the best way to check the
ground angle tool beside visually checking with an angle gauge?
55 deg and 60 deg is very close.

Wonder has anyone thought of making a magnifier shadow box that can
cast both the angle template and threading tool on to a screen at
a bigger scale for easy checking for the eyes.

This machine is popular in grinding industries and it cost a bomb!

Any cheaper ways to make one for home workshop? Or simply using a microscope and a light below to project a shadow up?

Thread: Laser surface gauge/marker project
18/10/2011 03:55:47
Hi comrades
 
Back again for more suggestions! Has anyone built a laser marker for short distance acting as a surface gauge and long distance for cabinet making?
 
Would appreciate anyone can forward relevant photos

Thread: Einhell Press Drill model SB501 being reliable??
14/10/2011 03:27:23
Hi comrades
 
Sorry if my question mislead anyone, as I have said getting a unit-1item (not a new distributor for Einhell) and I waited for the shipment referings to Einhell local agent to replenish their stock.
 
My other questions are asking end users of their experiences with Einhell press drill.
Anyway since this brand is not popular in the UK, don't think of any help except in Europe. Also did email some feedback to Einhell UK and Germany.
 
I doubt the grey ones were German made either when I inspected it few years back of their low price.
 
Thanks.

Hi Comardes

I have the intention of getting a unit this weekend, waited for new shipment close to 2yrs now. Was spellbound when I contacted the Einhell local agent the stock just arrived. Einhell is a German machine tool brand but many products now China made...

Having second thoughts that being made in China, I wonder did the Chinese cut corners like making the belt pulleys from cast iron to plastic or the guard cover being plastic instead of extruded metal casing?

If the pulleys were plastic will adversely lower the spinning torque and plastic guard will not last long before crack lines appear.

Have anyone used Einhell SB501most recent product painted in dark blue instead of the usual grey? I googled this press drill which many appeared in eastern European countries instead of UK.

Hope any kind soul would share some light over my plight?
Thanks inadvance.

Thread: Most stable small workbench design to date?
27/09/2011 17:26:14
Hi comardes
 
Wanted to make a survey about the rigidity of a small workbench. I often have this common problem that when I hacksaw bars in a vise the small workbench would rock too! I have a long heavy workbench which is ok for most jobs except my small workbench with fitted rollers many year back.
 
I got catalogues from Sjobergs (Sweden) wood-making workbench supplier and I studied their design. They have this common feature in all their benches a sturdy table top made of Beech wood and both ends are supported by 2 rectangular thick frames. Wonder this design is vibration proofs? Of course, the bench itself must contain certain weight.
 
A visit to IKEA-S'pore, I noticed that small tables are normally bolted to the wall beside to be stable-proof which I do not favour at all...any suggestions?

Thread: Tapping in a straight line
27/09/2011 17:03:00
Hi Guys
 
I learnt a trick to tap using a small bench press with the spring coil removed. I saw a Japanese website did this way using an old press drill without the motor.
 
I re-invented this idea using a workable bench press to pre-tap the hole once the tap bite sufficiently, I continue the rest on a table vise. Then of course with the motor off and belt removed by rotating the pulley by hand.
 
Tapping on the lathe is suitable for bigger lathe not Sherline or Unimate.
 
So any form can be tap easily as long it has a flat base and sides for clamping. This way one save the money buying a tapping press and save space for other essential machine for small workshop.

Thread: Building lathe/mill in cast of concrete?
27/09/2011 16:37:03
Hi Guys
 
I was delighted that this topic I posted many months ago re-surfaced! With more Chinese made machines saturate the markets one may wish to make instead of buying. Hence I strongly believe that this trend will pick up eventually. Though it was a lost trade. With the new selections of better concrete to withstand vibrations, one can build almost anything!
 
Hopefully along this line some MEW members would come out new products and share around so others can pick up and improve a step further...
 
Once again, thanks so much for the contributions, still on a learning curve.
I'm a member of Gingery yahoo forum, lots of tips there too. They cast alloy lathe/miller/shaper from their backyards. Most of them are from America.

Thread: Roller press - gear drive design?
29/08/2011 08:55:00
Hi Dick
 
Getting interesting here! Could you photograph the old dough machine you repaired?
Is the design simple? The internal belts, chain and gears? How many rollers are there?
 
Dough knife is just a thin sheet of stainless steel or plastic, possible to break it?! Normally wire is best for slicing cakes in layers to fill the in-betweens with cream and nuts.
 
I have not bake Hungarian breads before, only French Baguette, German and Turkey breads...able to get her recipe without making her mad?
 
Steve
 
p.s. Email me dough machine photos if too troublesome here: [email protected]
 
 
29/08/2011 06:47:06
Hi Dick
 
I smiled after reading your post! I did exactly the same way while I was in baking classes but my jigs were not in frame type. I used pairs of wooden strips of different height and placed inbetween doughs that I rolled over with a wooden roller, same concept right?
 
The dough roller press is just a thought.
Will think over whether this project is worth a try.
 
Thanks for your post
 
Steve

Hi Dick and Burner
 
Many thanks! Will study your design but still I may need a movement between 20mm to 30mm at least...as I'm making a dough press not a sheet metal roller press.
 
Thought of using bicycle type spoke gears and chain with ample play adjustment inbetween. Yet to ponder upon...

Thread: Drill Sharpening Jigs - Advice please.
26/08/2011 06:56:17
Hi John
 
Sorry for the late reply! I got a solution just for that...it will be good to build a sharpening jig than buying as this is endless....so many out there!
 
For drill bits I used the Tormek concept to grind 4 facets sides drill bits. See my photo.
 
For end mills I made a simple tool and cutter jig with influence from Quron, Deckel So and only recently Bristol Cutter grinder from MEW. See my photo.
 
With these 2 jigs one could sharpen anything. But to sharpen the flutes of end mill is a challenge though. Also drill bits smaller than 3mm is best done using a hand grinder for better control than a bench grinder.
