Are loft lie adjustments possible at Titleist Thursday?

They do not have repair tools, just clubs and launch monitor. They can write down specs for you and you can take your clubs to your local club repair shop... they typically charge $5 per club for bending.

Titleist Thursdays are just for new club fittings. They only have standard fitting sets with the removable heads and shafts for drivers, fairways, and irons. Usually only the 7 irons in the multiple head styles. There is no bending machines or things like that. They have 7 irons that are pre-set at standard, flat, and upright to test against your swing. If you need to see if your lofts/lies are off, you need to send them in to Titleist or your local pro shop for adjustment.

Not to the ones I have been to. Normally Titleist Thursdays are done on a range with a fitter and lots of clubs. They are there to fit those who have signed up and have an appointment. I would recommend going to a good golf repair shop in you area and have the tweaked. Check for fitters in you areas they do them in their shops, i.e., PGA, Edwin Watts, etc. There is normally a charge for this service. Where do you live?

I doubt it, I've not seen one at the Thursday events I've attended. At these events you will typically hit current fitting heads, which can be adjusted, on various shafts to see what works best for you. You will likely need to schedule a dedicated fitting event to see what changes need to be made to the loft/lie of your current clubs and then have a repair person/shop make the changes.
