Thread: Thiel 158 problem
13/11/2011 14:53:13

Hi Bob

Thanks for your suggestion. I do have a manual, but it must be based on a later type of machine than mine because there are several differences in it and crucially no shear pin is shown.

Does any reader have a good working knowledge of the Thiel 158 milling machine - or know anyone who does?

I have lost power feed to the Y axis. There must be a shear pin somewhere that has failed, but where?! I know about the main one on the left hand side of the column and that one is intact.

Hopefully someone will be able to help.

There was also the Mery engine of about 1890. Double acting 6(?) stroke. Casting kits are available from Morrison & Marvin and is a very popular engine build in the US.

Is anyone familiar with the workings of the Thiel 158 Duplex milling machine?

Whilst making brackets for fitting a DRO, I removed the Y axis power feed stops and the power feed overran its travel and the Y axis shear pin sheared.

Question: Where is the Y axis shear pin located? I know the main one on the left hand side (and it is intact), but I believe each axis has its own shear pin.

I have asked this question on a couple of other fora, but so far no response. Is the Thiel such a rare beast?!

Thanks Ian and Johan.

Seems like I need to look for an old fashioned Fluorescent starter!

Hello all

Does anyon know a source of low tension coils in the UK?  I need one for an igniter fired hit 'n' miss engine. Hemmingway does not stock them.  I would imagine a call to one of the US engine specailists is required, but which one?

If no source is known, is it possible to use a normal car / bike / lawn mower 6v coil and just use the secondary winding (keeping the primary out of circuit)?

Just to let you know I arrived home in Ireland today from working in Saudi Arabia.  My survey will be in the post tomorrow morning.  Hope it is not too late!

Perhaps someone like College Engineering Supplies would be able to give you a definitive answer.

Alyn Foundry ceased trading from April 2008 for various reasons.  Graham Corry still retains the patterns and drawings for the designs (although not all the designs were drawn up).

The business was/is up for sale, but the asking price was a bit unrealistic considering today's economic climate.

As far as I know he has no stock of any castings for his engines.

At the moment I am using the Jerry Howell Buzz coil circuit on my RLE Hit and Miss engine, these circuits had to be made up from components, the systems on the above site are ready to go which sounds good.

 Unfortunately, Jerry Howell doesn't produce the buzzcoil circuit kits any longer.  They are now available from

but at a huge increase in price.

Or you may want to go the deLuxe route and try
