Clarkson Tool and Cutter Grinder Build

[Colin H]

As I haven’t finished my other projects I thought it time to start another one!

Picked up a grinding head and table minus a base from local chap.





I was going to mount on a tool cabinet but couldn’t bring myself to not have the base. Then another chap had a base complete with another spindle and table and also centres with universal head!

Have now started work on paint for base.

Used the scrape to remove as much paint as possible.





Then a sand down and rust converter applied.



Moved onto high build primer which didn’t react on this machine like lathe did.



And put first coat of enamel in last night. This was grey I bought incorrectly for my Colchester and looks nice I think.



Second coat later which always looks much better.

Next up will be base mounts and then scraping in slides etc.

Hoping to get done over Christmas week off

Nice.
Looking forward to further updates.

I started the machine itself today.

I put the rotary surface of base plate on the surface plate and rocked all over the place. Wear was at front of machine as you would expect with weight hung off front.

This machine is all milled / planed as standard on contact surfaces but using this as extra practice getting my curl scraping practice.

Dodgy setup in mill as only way I could get travel was with the fly cutter of death!



I then put the table base that mates to the surface above on surface plate and was flat enough to not rock. I then scraped a little to break up and get blue. Then proceeded to scrape it in.

In picture here I am finally to rough with a curl scrape without picking up scraper off surface.




Around 7 passes got me to here.

I’ve stopped for day and hopefully get a little done later tomorrow to finish it and then use as master to scape base surface.

Following this may shame me into restarting the rebuild of the (two and a half) Clarksons that I own !

I will never for the life of me understand scraping......

Keep a small plate for jobs like that. Mount the part upside down on the bench and put the plate on top to take a print. That way the print is not affected by the chunknof weight hanging off the side of the part.

I think we just need to get something and start having a go.
It is something I would also like to be able to do.

 

[Mark Davison]

@Pete. Was kind enough to give me some tuition a couple of years ago.

I have one and a half

I thought I did for a while which is much worse Then attended a course with @pressbrake1 and now know what I don’t know. I learned what I should be doing so can now scrape without ruining parts and make decent surfaces that are aligned. Lots to learn yet though.

Yeah I had fun trying to print it first until I found a technique. I have a small bedding plate that’s too small and one that’s too big, typical!

Axminster tools do a ****ty cast iron one the right size and being iron I could scrape it in against my inspection grade table. That said the table is due a check really as I have scraped a few jobs now so may have some wear. Time to find an auto collimator or build a repeat meter

That’s what I did for some time before taking class. If you can find somebody who knows there stuff to be there in person it’s well worth it.

Trying one of these cheap panel mount inverters for the grinder. It says 1.1kw max but I reckon it will let smoke out at that

Makes for easy mount in control panel and no faffing with pots, buttons etc. £45!!

Just got rid of a 10" surface plate which is ideal for the job.

I do have some 10" cast iron plates though which if you bolted some handles on would do a nice job

That's tiny. I've mounted one of the generic AT1 VFDs inside the column. One of those would have been easier and neater.

Thanks Brad, I’m pressing on with it right now but may look at one for later thanks.

I was thinking of mounting in column but was concerned about the dust and grit in there. Maybe put a little cover over three sides inside
