Member postings for steve bowden

I am a member of the Harrison forum and every time someone posts to it I receive the message as an E mail which includes every reply to the subject also.

This is hundreds of E mails per month. How do I stop this? I still want to remain a member of the forum but to receive no E mails or just those that reply to a posting I make. Please read this carefully and reply in full detail making the assumption I am not a wizz kid on computers

Thanks Steve

As previously mentioned the sheet is 1220 x 1220 mm. I will use 20 thou material if I can get it otherwise 32 thou which I can get locally. Some thin plastics are 5 times the price of paxolin. I need to cut strips off it 1220 mm long and various widths,the widest being 104 mm and the narrowest 46 mm..

I could then stack to cut these long strips or cut individually to give widths between 65 and 141 mm. I would then have a number of rectangular pieces the smallest being 65 x 65 and the largest 104 x 141 mm.

The pieces then need 3/32" holes in them. The largest piece would have 165 holes 3/8" apart in all directions but only 1/8" from from the edge.. This is not a commercial operation and I have only one sheet to do. As regards a different material it needs stiffness and many plastics do not seem to be available so thin and surely blow moulding plastics would be floppy.

I do know the originals were punched way back in the 1930s of which I have no experience (thats both punching and the 1930s). Would a flat ended 3/32" silver steel punch work or would it need to be hollowed out to give an edge? If I make a steel plate with all the holes in I would then perhaps have the option of drilling or punching one hole at a time. I suspect though that whilst a could drill a few at once in a stack they would have to be punched one piece at a time. I suspect also for punching I would also need a guide plate top and bottom.

Laser cutting and drilling sounds interesting but I expect prohibitively expensive

I will send a further post if I can with a scan of the finished product but I need to shut down my computer before I can fire up my Scusi scanner

Thank you all

Regards Steve

I should have mentioned sheet size is 1220 x 1220 mm and accuracy + or- 0.5mm required so I think it needs to be stationary whilst cutting. Would not the three teeth rule apply requiring a bandsaw blade of some 150 TPI?

Regards

Top this one if you can. I need some comressor gaskets from the USA. Cost is $7. Postage is $49.50 by courier and incudes the import duty and vat. However that is zero below £15 value. Posted air mail by USPS would be $2.40 for the size and weight. Needless to say I no longer have air conditioning in my car. I could afford to lose a lot in the post before hitting $49.50.

I need to cut accurately 20 thou and 32 thou paxolin sheet. It is prone to shattering so any suggestions would be appreciated. I then need to drill a multitude of 3/32" holes at 3/8" spacing for which I could stack them but what would be a reasonable thickness for the stack to ensure the holes do not run off. I believe a 90 degree drill point is recommended.

I have a delapena speedhone which has a noisy nose bearing and I have been unable to puzzle out how it comes apart. The machine carrys David Brown badging which i think means mid eighties.I spoke to Delapena but just got its old we don't have any details. Can any body advise or E mail me a manual/ exploded diagram.
