Does it take time to see your review Michael or has it been removed?

Oh dear

i just ordered a 25 piece set of the turbo drills today after all the rave reviews

some of the 303 protectant arrived and it seems to have worked well on the sticky grip oF A samsung camera..after 5 minutes its no longer sticky but only time will tell if it lasts a while

Taps and die boxes are easily available for wood screws such as these

they don’t conform to and metal working taps AFAIA

On my 2x72 grinder i did buy some shafts already covered with rubber about 5mm thick a selection of diameters ( i cant remember where now though) i needed a special size so made a alloy shaft and covered it with heat shrink tubing…its worked well

How about warm your Perspex in a domestic oven …not for long as its only 1mm thick..then drape it over a former like a big ish ball allow to cool..

Oh and Martin j many thanks for that suggestion on how to make the bush..i was going to use your idea if my part didn’t work however it seems fine so far

Vic

i can see that the Axminster one just has a knob…do you know how that works? Is it on a hinged spindle to adjust tracking? The sorby one whilst needing the tommy bars once set I’ve never adjusted it in all the time I’ve had it perhaps 7 years or so with many hundreds of belt swaps and new belts.

this is my finished machine for use in my metal working room…the genuine one is by my woodturning lathes

The original shaft is from a Robert sorby proedge

its a very elegant way of tracking the belt

I’d just buy a new(sh) motor 4 pole of at least 375watt (1/2 hp) or bigger if you can squeeze a bigger one in

make sure its dual voltage

i bought 2 last week on eBay for £40 each both new and unused

Well i bodged it

turned the lot as one screw cut the threads and then cut with the bandsaw (1mm kerf) about 3/4 the way through the 35mm boss then squeezed it in the vice and welded it up

measures as well as my original

Its for a belt grinder the tracking adjustment for the pulley

Brilliant thanks to martin and robert

Well its not eccentric its bent

I have this part that i want to replicate

The shaft to the left is concentric to the middle boss but the boss is 18mm on one side and 19.3mm on the other making the shaft to the right at a shallow angle.

how can i do this?

When about 13 my friend and i were told about sodium chlorate and sugar by an older boy . We emptied our parents shed and kitchen of the ingredients and mixed them into an innocuous pile and lit it with a match (at arms length luckily ) the resultant explosion just put a big smile on our faces and we spent the whole summer making rockets etc.

our mothers couldn’t understand where all the sugar was going and after the sodium chlorate was all gone so was our pocket money buying new supplies from garden shops.

When i make them i just drill to the small end diameter and then slowly let the reamer cut the whole taper.

lots of cutting oil and very small increments of travel < 1mm the flutes fill rapidly and withdraw and a toothbrush to clean the flutes rinse and repeat

the bsa’s had one camshaft with 4cams on it certainly but we are all talking about one cam operating both inlet and exhaust duty’s

Some pictures here of a ner a car engine ( blackburne) showing the arrangement

The table does hold as it would with a handle but when i want to lock the table i have a hydraulic cylinder and pump (hand op) that does the job.

it may seem overkill but this is a drill in a very tightly packed workshop so its not easy reaching round for a handle and the locking screw

Andrew

thats just a 24v dc parvalux geared motor driving the shaft which lifts and drops the table and a switch mounted on a flying lead so that can mount on the table where i can get to it
