HELP parting tool blades

[jeldred]

Is there anybody out there can help me in sourcing a replacement blade for the George Thomas rear tool post.
No problem in sourcing the 3/32 " blade but unable to find a supplier who can supply the 1/16" by 1/2"blade.
Any help on this matter would be appreciated, or if anybody has )a spare one and would be prepared to sell it please let me know.

Hi Jeldred,

I bought a T type parting tool from Mattools on Ebay which uses 1/16"x1/2" blades. They also sell spare blades for them. RDG tools also sell a very similar one which may use the same size blades.
I think the Geo Thomas design uses the standard tapered blades?

Tried to ring you this afternoon, but your 'phone was engaged. (I hope it will be very happy once it's married !)

This may sound like a silly question, but:-I have a Chester DB8 lathe ,I want to tap the cross-slide (8mm ?) to mount a vertical slide, also rear tool post and parts for boring,facing etc. Question -is there any standard spacing or pitching, or any recomendations?

[brozier]

Different manufacturers have difference spacings.

Do you have a vertical slide? What are you going to use?

I can tell you the spacings on the Myford Fixed slide if that helps. Do Arc Eurotrade sell them for the C3 lathe?

Cheers

Brozier,-Re; cross slide drilling, no dont have vert slide yet,might get one for C3,might use topslide & angle plate,sellers w'ont give any figures. Do not know how this query came up in this thread,but will get the hang of it eventually. Any help gratfully received.

One thing you might want to consider Longor is the use of a sacrificial plate to screw down onto the cross slide? Holes in four corners of a plate, spot through to cross slide, drill and tap cross slide, and then you can drill and tap as many holes in whatever positions as you like in this plate. Has also been called a milling table.

Circlip-exelent idea,also seen a bolt down "milling table" that might do the job, can also be spotted underneath to clear oil nipples etc. Will 4 M8 bolts be enough ?

I use circlip idea to bore cylinders between centres , see my thread on it in this forum . I ground a 1/2" plate in tech college 25 years ago and use it for all purposes and still use it . I remove the tool post and use the same mounting for the plate .It works fine for me .

[circlip]

M6 would be better. Dependant on how thick you can go, you may be able to put tee slots in it. It's good to have an endorsement by one of the forum masters in Shawkie, goes to prove that some of the old ways are still valid DESPITE DRO's ;D
Regards Ian.

I love rear parting off so much I even made one for the Unimat 3, this is a plate bolted to the little cross-slide and the new tool posts attached.

Saves all that junior hacksawing of the motor.
